The General Purpose Input/Output pins allow you to control and interact with the real world.

Switch on a LED

Let's do the usual material "Hello World": switching a LED.

Just build as the photo shows.

Learn more about the hardware here: Learn more here : http://thethingbox.io/docs/GPIO-Book.pdf

More details.

Here is the simple flow we will build with the graphical editor.

Go to http://theThingbox.io and download the SDCard image you can flash using the Etcher app ( https://www.raspberrypi.org/magpi/pi-sd-etcher)

Use your web browser to access the visual editor using the network name you gave in the setup process.

We will build a simple flow with the GPIO node.

Edit the node to set the GPIO port to use.

just hit the deploy button and now, by clicking the Go button you can switch the LED on and off.
